Identify oxidation number of Sulphur respectively in SO ₂ and SO ₄²⁻ .

Options

  1. A+6 , +4
  2. B+4, +6
  3. C+4, +3
  4. D+3, +4

Correct answer

B. +4, +6

Step-by-step solution

Let the oxidation number of Sulphur in SO ₂ be x . x + 2(-2) = 0 x = +4 Let the oxidation number of Sulphur in SO ₄²⁻ be y . y + 4(-2) = -2 y - 8 = -2 y = +6 The oxidation numbers of Sulphur in SO ₂ and SO ₄²⁻ are +4 and +6 respectively. Answer: +4, +6
